When attempting to use an AttributeConverter that converts the attribute to a Byte type, hibernate generates an error of

Caused by: org.hibernate.MappingException: No Dialect mapping for JDBC type: 1998767043

Where the integer value listed seems to be some random value.
However, using Short, works.
On several projects, we're wanting to utilize byte values to store enumerated types instead of inefficient text strings.
For now, we're working around it by using Short instead, but obviously this uses double the size per enum per row.

I've attached a small test project to exemplify the issue. can use

mvn clean verify -Phibernate53
mvn clean verify -Phibernate54
mvn clean verify -Phibernate60

to run with 5.3.17.Final, 5.4.15.Final, and 6.0.0.Alpha5 respectively.
